Yeah, Luke Cage and Iron Fist are both pretty awesome. Daredevil is good, too, if done right. I'm not familiar with Jessica Jones, but she sounds interesting -- she can fly, which I believe would make her the first Marvel hero from the Marvel Studios movies/TV shows to be able to fly other than Thor when he uses his hammer.
Apparently, Isaiah Mustafa, "the Old Spice Guy", wants the part of Luke Cage so much he's
put together his own teaser video for it.
